Resort, swim, and eat is probably your best bet to be in bed by 11pm. The more adventurous option is to get dinner at one of the monorail resorts, and go around and stop at poly, contemporary, and grand floridian. You'd then go to the MK monorail stop, walk to the buses to take back to CBR - do this before park close though or there will be a crowd. This is cool if the kids would like sight seeing the resorts and don't mind a little walking, which seems to be a rare thing these days! lol!
